The hub c'is bolted on the to abut the ends of the thimble z.axle through the flanges c. In order to more clearly explain theutility,

I shall now describe the adjustment and operation. The inner sides ofthe split hub are carefully faced off after being bolted on the axle, sothat the gear 71 may fit closely thereto, and the outer circumferentialsurface of the split hub is turned true, so that it may be concentricwith tread of axle-wheels. The gear-wheel his bolted securely to thesplit .hub o, the latter forming the bearing for the said gear in itsrevolutions with the axle. The inner periphery of the sleevej is notdesigned to bear on the axle at any part of its surface. The rotation ofthe gear h with the axle a turns the gear .9, which is journaled in thearm g from the strap 1).

It will be seen in the following explanations that the revolving of thesleeve will in no wise affect the position of the gear 3. The positionsof the sleeve j and the axle a must always be identical-that is, anyvibration or sudden jar affects bothfor the sleeve extends from the gearh, and this gear through the separable hub bears on the axle and turnstherewith.

The adjustable and swinging support allows the truck and axle to haveconsiderable lateral movement, which is extremely essential, as suchlateral motion is constant and is especially emphasized in roundingcurves.

It will thus be seen that the rigidity of the arm q is much relieved.

The main object of this invention is to provide for the exact meshing ofthe teeth of the gear-wheels, not withstanding the changes of positionsof the axle and the truck while in travel. This is to a large extentaccomplished by the adjustable support of the arm q through the turningof the rod y in the rings 00 and the consequent raising and lowering ofthe rod y. The springs 2 allow a limited lengthwise movement of the rodin the thimble z to account for the different vertical positions of theaxle and the truck in relation to one another. It will be thus seen thatat each circumferential movement of the sleeve the gear assumes aposition relatively the same radial distance from the center of theaxle. The gears are always in engagement one with the other, yet theyare free to move with the changes in position of the truck or axle andstill be in constant engagement.

The adjustment for the centering of the gear h in order that it may beconcentric with the tread of axle-wheels is a very important feature inthis device, and the means for accomplishing this are simple andeffective and can be readily understood by any ordinary mechanic.

As before explained, the parts of the gear are bolted to the projectingflanges of the split hub through the slots f. This will allow the saidbolts a considerable movement radially from the center of the axle. Themovement of these bolts is controlled by the set-screws i, insertedthrough the bosses g,and as there is an intervening space between thethat the wheel is concentric with the tread of axle-wheels.

The difficulty hitherto experienced in centering of wheels is wellknown, and consequently the ease and facility with which by the simpleturning of the set screws the wheelmay be centered will be muchappreciated by mechanics and those otherwise interested. For instance,in this device a positive accuracy can be attained in a very short timeby adjusting one screw after the other until they are, as beforeexplained, equidistant from the circumference.

When the gear h is concentric with the axle, the strapp is bolted in acircumferential groove on the sleeve j, and, as explained heretofore,the gears is always at the same radial distance from the center of theaxle, and therefore from the center of the sleeve and strap, for withthe gear it they are concentric with the axle. Consequently the gear 8may be engaged by the gear h equally well in the varying positions ofthe arm (1 caused by the jolting of the truck or the axle.

The shaft 15, which is rotated by the gear 3, extends into a dynamo orother machine requiring the power transmitted by the revolutions of theaxle, and in extending this shaft it is probable that a universal orother suitable joint will be required intermediate of the distancebetween the dynamo and the gear. However, I have not shown this in mydrawings, as it is well known and needs no further explanation.

In Fig. at I have shown a plan view of an alternative form of gearing,in which the arm from the strap is further extended, so as to form abearing for the gear heretofore indicated, as s, in order that the saidgear may engage the spur-gear instead of the bevelgear h illustrated inthe other drawings. The form of the swinging support and the generalarrangement may be precisely the same as in that already described, andit must be here understood that I do not confine myself to anyparticular form of gearing, as many may be adopted using substantiallythe same arrangement.

The use of gearing for transmitting power from revolving axles intransit appears to be the only positive manner of transmitting powerfrom the said axle, as there is no slipping, as in belts, and verylittle wear, and all the mechanism connected therewith may be suitablyincased, so as to preserve it from the inclemency of the Weather, thoughthis will of a hub having projecting flanges therefrom,
